Due to be released at the Detroit International Auto Show from GM: The GMC All-Terrain HD concept. You may be familiar with the half ton Sierra All-Terrain (different wheels, grille, interior than a standard Sierra) but the HD goes a little more off the map…. Powered by the 6.6L Duramax diesel, the truck also has an extra 3 inches of ground clearance, is 4 inches wider, and rides on 20-inch wheels wrapped in 35-inch offroad tires with Fox off-road shocks (same as used on the Ford Raptor.)

Inside, the concept comes with Denali-spec interior and satin metal finishes – much like it’s half ton counterpart, but also has the upcoming next generation 80 gB hard drive that we’ll be seeing across the full GM line in the next few years. Being a concept there are no plans to actually produce the truck… yet… but if it were to be produced you would likely see it come from a third party firm as opposed to rolling off the GM production line looking like that.

Will be excited to see the concept at the Detroit show, and maybe find a few more details about possible production of the truck, but for now enjoy the pictures.

Pickuptrucks.com is reporting that GMC is going to unveil a preview of its next generation Sierra HD at the North American International Auto Show in Detroit in January. For the 2011 model, GM introduced an all new chassis and an updated Duramax diesel V8 engine, but the body style has remained the same since its mid-2007 model year launch. More news to come when GM officially announces the concept, we’re looking forward to it!

Not only does the 2011 GMC Sierra HD pickup offer the most power in its class, and a Denali trim level, but you can count another win for The General over its heavy-duty pickup competition – best-in-class towing and payload figures. The new trucks will now be able to tow 21,700 lbs in fifth-wheel configuration and 17,000 lbs with a traditional ball hitch, as well as handle 6,635 lbs of payload. The new trucks best their closest competitor – the Ford F350 – by a whopping 1,000 lbs in conventional towing, and 100 lbs in fifth wheel configuration.

Based on these improved capacities, the Sierra HD becomes the most capable heavy duty pickup on the market. The trucks start production next week, and we expect to start seeing them on the lot sometime in late summer. Come on in and test them against the competition, we know you won’t be disappointed!
